Iv'e seen the beta 7 IE, it kinda looks like Safari. Imagine that Microsoft gets inspired from another OS.
Here's a video where the IE 7 developers are going ape **** about how "Longhorn Loves RSS", even wearing a shirt saying that. Safari, FF and Opera have saw the RSS light long ago yet Microsoft jumps in and acts like they created the protocol.
I will admit that Microsoft does have some interesting plans for RSS in IE 7. Also, in an interesting note they mentioned the RSS extentions featured in IE 7 will be available to everyone and even made mention of Linux developers being able to incorporate them into their projects. It will be released through Creative Commons, a first for Microsoft I believe.
